"A Method Of Fabricating Structured Particles Composed Of Silicon Or A Silicon Based Material And Their Use In Lithium Rechargeagble Batteries"
Abstract: The present invention provides a process for etching silicon to form pillarsy, especially for use as the active anode material in Li-ion batteries, the process is simple to operate on a commercial scale since it uses an etching bath containing only a small number of ingredients whose concentration needs to be controlled and it can be cheaper to operate than previous processes. The etching solution comprising: 5 to 10M, e.g. 6 to 8M HF 0.01 to 0.1M Ag+ ions 0.02 to 0.2M NO3- ions, and optionally SiF6 2- ions alkali metal or ammonium ions, and incidental additions and impurities Further NO3- ions, e.g. in the form of an alkali metal or ammonium nitrate salt, are added during the etching process to maintain the concentration of nitrate ions within the above range.
